摘要
成分连续变化的梯度材料广泛应用在航天航空、生物医用和汽车等领域,但传统的成形制备技术存在着较大的冶金缺陷,影响梯度材料的综合性能,而增材制造技术可以有效解决传统制备方法的冶金缺陷.本文对增材制造梯度材料进行了概述,总结了增材制造梯度材料的主要技术,讨论了增材制造梯度材料的组织结构与性能的研究进展,并对本领域未来的研究前景进行了展望.
Abstract
Functional gradient materials with continuous change of composition are widely used in military,aero-space and automotive fields. However,the functional gradient materials prepared by traditional methods have large metallurgical defects,which restricts the performance and application of materials. As a new manufacturing technology,additive manufacturing can effectively solve the gradient material forming problem. An overview of additive manufacturing gradient materials are given,the main techniques of these materials are summarized,their microstructure and properties,and the future research prospects in this field are discussed.
